Aviation ASSURED PNT

The Aviation ASSURED PNT program is designed to enhance the Army's aviation capabilities by ensuring reliable access to Position, Navigation, and Timing (PNT) information in contested environments. This initiative focuses on modernizing existing systems and integrating new technologies to provide aircrews with trusted PNT data essential for mission success. It aims to develop alternate, contingency, or emergency PNT solutions that allow aircrews to complete missions or recover safely even when traditional GPS signals are compromised.

Key components of the program include the integration of advanced Global Navigation Satellite System (GNSS) GPS receivers, anti-jam antenna systems, and navigation equipment with improved resiliency functions. The program also explores alternative PNT solutions that can operate independently or in conjunction with existing systems. A significant aspect of this effort is the Embedded GPS Inertial Navigation System (EGI) and Enhanced Aviation GATM Localizer Performance with Vertical Guidance (LPV) EGI (EAGLE-M), which introduces new military code GPS signal security to bolster PNT capabilities.

The Multi-platform Anti-jam GPS Navigation Antenna (MAGNA) is another critical element, providing a GPS anti-jam adaptive antenna system that mitigates the effects of jamming by rejecting interfering signals. This ensures continuous access to GPS-provided PNT data in degraded environments. Additionally, the Doppler Global Positioning System Navigation Set (DGNS) Upgrade program supports efforts to reduce space, weight, and power requirements while meeting current and future civil airspace needs.

The Aviation ASSURED PNT program supports Joint All-Domain Operations (JADO) by enabling precision navigation and approach capabilities in both civil and military airspace. It addresses the need for robust PNT solutions across various aircraft platforms, including UH/HH-60A/L/V, CH-47D, AH-64D/E, and others. The program's objectives align with maintaining operational readiness in challenging environments where traditional GPS signals may be unreliable or unavailable.
